Why Wait for a Pot to Boil? If a recipe asks you to blanch something in hot water, you don’t have to stand around waiting for a pot of water to boil. My Aunt Rose taught me to blanch vegetables quickly by adding cold water to a tea kettle until it is half full. As soon as it boils, pour the water over your vegetables sitting in a colander in the sink. Instant blanching!
